Since Tuesday morning, women of all ages, ethnicities and backgrounds have shared their stories on Twitter.

Some women tweeted about being catcalled at ages as young as 9 or 10 years old. Other women shared stories of sexism in the form of sexual comments made by family friends at a young age or sexist dress codes enforced by teachers. The hashtag was also used to share darker stories about rape, molestation and victim-blaming.

As Bates explained to The Huffington Post in a recent interview, many of these smaller incidents of sexism can lead to more violent and serious abuse. “We’re often told not to make a fuss about street harassment or that we’re getting upset about nothing if we talk about media sexism, but you can see from the stories we receive that these things have a [domino] effect,” Bates said. “When you normalize these everyday pinpricks, they create an environment that makes the more serious incidents possible.”

Scrolling through the hashtag, which now has thousands of tweets, serves as an important reminder that all women experience some form of sexism — and many experience it at a very young age.
